Question

What is the signed magnitude c of the projection p correct choice above, find a number c such that po of z) onto z2)? More precisely, let u be the unit vector in the direction of the cu Express your answer in terms of a 1 for a1, a 2 for a2, and a 3 for as. (a 1+a 2V(a 3) a1+a What is the (vector) projection p) of z) onto ?Express your answer in terms of the signed magnitude c, z), )|, z2), ||z(2) (Enter x1 for r), norm(x1) for lz), x2 for z2), and norm(x2) for a Do not worry if the parser does not display properly, the grader will work independently. For proper display, enclose x1 and x2 by brackets, eg. (x1)) (input update: In the last question, the grader has been updated to accept answers in terms of c instead of norm(p). Earlier correct answers will remain correct.) Pamsal STANDARD NOTATION we 1. FIEh (0/3 59) x 1. (d) 0/348 tA Recall from linear algebra the definition of the projection of one vector onto another. As before, we have 3-dimensional vectors a) -E and a Which of these vectors is the direction of the projection of ronto 2 e)
